[目的]探讨不同浓度白头翁水煎液对离体蛙心的影响。[方法]采用斯氏蛙心灌流法制备离体蛙心标本,分别加入不同浓度(100%,50%,25%,12.5%)的白头翁水煎液。观察药物对离体蛙心的作用。[结果]四种不同浓度的白头翁水煎液均能有效地增强蛙心的收缩张力峰峰值,同时也使蛙心收缩频率明显减慢。[结论]白头翁水煎液对离体蛙心有明显的影响。
[Objective] To investigate the effects of different concentrations of Pulsatilla decoction on isolated frog hearts. [Method] The specimens of isolated frog hearts were prepared by Cryptanalus frondosa perfusion method and the decoction of Pulsatilla was separately added at different concentrations (100%, 50%, 25%, 12.5%). Observe the effect of drugs on isolated frog hearts. [Result] Four different concentrations of Pulsatilla decoction could effectively enhance the peak-to-peak contractile tension of frog hearts, and at the same time, the frequency of contraction of frog hearts was significantly slowed down. [Conclusion] Pulsatilla decoction had obvious effect on isolated frog heart.
